Flat Track Gravity Research (BEAMNNG)

I ran the default truck down a flat track (starting from stand-still), decreasing the gravity (starting at -20) by one each time until I reached -5 (past this point cars start to float off track). Here are my results:

From this data I can conclude that gravity has little affect on speed or acceleration on a completely flat track. However, -11 seems to be the optimal gravity here as it took the least amount of time for the car to reach the goal. Come back later for more pointless BeamNG research!

Optimal race gravity (BEAMNG)

I decided to devise a test to find the optimal race gravity in BeamNG. To do this, I ran an automatic Sunbeam (t avoid any anomalous results from occurring due to changes between gear shift times) down a track that contained both up-hill and down-hill sections as well as flat plains to see what gravity had the car come down the fastest and with the less slipping. My results show that, out of all the testes gravities, -12.5 gave me the fastest results. I will perform further testing to confirm this or  to find an even better gravity, so stay tuned!
